STAPLEIQSETTING IMPLEMENT.

To all whom it may concern:

Be it known that I, JOHN H. KERSTETER, acitizen of the United States,residingat State College, in the county of Center, State ofPennsylvania, have invented certain new and useful Improvements inStaple-Setting Implements; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it apper-tain's to make and use thesame.

The present invention is directed to improvements in devices for drivingstaples, and has for its object to provide a device of this character soconstructed that a number ofstaples can be held in position to besuccessively driven.

A- further object of the invention is to provide a device of thischaracter which is exceedingly simple in construction, and one providedfor holding a plurality of staples which are fed one at a time toaposition tobe driven by the driving rod.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which Figure 1 is a side elevation ofthe device. Fig. 2 is a front view. Fig.3 is a sectional view on line 33of Fig. 1. Fig. 4 is a similar View on line 44 of Fig. 1. Fig. 5 is alongitudinal sectional view. Fig. 6 is an end view.

Referring to the drawing, 1 indicates the handle, said handle having alongitudinal bore 3 formed therein, and in which is slidably mounted aspring pressed drive rod 4, the lower end of which being provided with acurved recess 5 for engaging the bight of a staple. The lower end of thehandle 1 is provided with .a cut away portion 6, the purpose of whichwill appear later.

Removably engaged with the lower end of the handle 1 is a plate 7, saidplate having its lower end formed with a horizontal flange 8 whichsupports the outer edge of the staple supporting bar 9. The inner edgeof the bar 9 is spaced from the adjacent walls of the handle 1 so as topermit the passage of the staples as they slide from the bar, wherebythe staples will be successively positioned under the drive rod 4.

Specification of Letters Patent. I

Application filed April 21, 1916. Seria1No. 92,744.

Hingedly associated with the handle 1 a spring pressed guard 10, whichis substantially semi-circular Patented Nov. 21, 1916.

in cross section so as to receive the upper edge of the bar 9, saidguard serving to hold the staples against accidental disengagement fromthe bar 9. The outer end of the guard 10 is provided with a yoke 11, thelegs of which straddle the bar 9 so as to preve n oil the outerend ofthe bar.

The handle 1 has associated with its lower end a claw bar 12 which isfor the purpose of pulling nails or staples.

The handle 1, bar 9 and guard 10 are preferably formed from aluminum,while the drive rod is formed from steel.

In use, a plurality of staples are engaged with the bar 9, and the guard10 under the action of its spring 13 will The handle 1 is held in ahorizontal position at one end so that the bar 9 will be directedprevent the dis .engagement of the staples from the bar.

t the staple sliding upwardly thus causing the staples to gravitatesuccessively into the path of movement of the drive rod 4 which beingstruck a sharp blow will drive the staple into the post. 4

The device is particularly adapted for use in stapling fence wires tothe supporting posts, butit will be of course understood that it can ,beused in any other connection seen fit. y i

What is claimed is I A device of the class described comprising a handlehaving alongitudinal bore formed therein, a spring retractable drive rodslidable in the bore, a staple supporting bar having its inner enddisposed adjacent the inner end ofsaid bore and so arranged that thestaples will be successively fed into the path of movement of the driverod, a spring pressed guard carried by the handle for inf closing oneedge of the staple supporting bar, and a yoke carried by the outer endof the guard and arranged to straddle the supporting bar to retain thestaplesthereon, as

and for the purpose set forth.

In testimony whereof, I affix my signature, in the presence of twowitnesses.
